Battlefield for me. learning ballistics, scope sway, and drop helped me become a better sniper in all games, even though most dont implement the same dynamics. In this game its all about the weapon. Prudence II is my personal favorite. Perhaps adjust your sensitivity. If you are really bad, use a sticky note, cut out a dot, spawn in patrol and dont move. The dot is true middle. Place sticker on tv and when a head is close to the sticker in pvp ads and shoot...i cant stand a sticker, its obnoxious to me and always in the way, but it really helps others.
